WebJan 9, 2024 · Although Boltzmann published his famous definition of entropy in 1877, the constant of proportionality in Boltzmann’s definition, was not identified as Boltzmann’s constant until 1900 when Planck published his analysis of blackbody radiation ( 1900a, 1900b ), where he identified the constant as k and named it after Boltzmann. WebThe Boltzmann constant ( k or kB) is the physical constant relating energy at the particle level with temperature observed at the bulk level. It is the gas constant divided by the Avogadro constant : \ k = R/N_A . It has the same units as entropy. It is named after the Austrian physicist Ludwig Boltzmann .
